Windows 7: Windows 7 - BSOD: IRQL_NOT_LESS_OR_EQUAL with ntoskrnl.exe

Windows 7 - BSOD: IRQL_NOT_LESS_OR_EQUAL with ntoskrnl.exe


I have had this BSOD a couple time over the last 9 months or so. The first few times it happened maybe every couple months. But it has now happened twice in the last two days.

I used a program called BSOD viewer to search the issue. At first I found something related to Logitech's setpoint software so I updated that and the BSOD didn't happen for a while. But now I am getting them again, and at least the most recent two times I was watching a video on youtube.

I am running Win 7 Pro (my key is from MSDNAA). System specs are as listed in my profile. The system is about 1 year old ditto for OS install.

Edit: I forgot to mention I ran memtest 4.2 for a total of 13 passes (4 + 9) and no errors were found.

Edit 2: In the mean time I have had another BSOD. This is very strange normally it happens once then it doesn't for a couple months. I have redone the perfmon and the other procedure so as to include the newest info. This BSOD also occurred while watching a video, though this time it was on Also these videos are watched using chrome.

Older versions of ASACPI.SYS are a known BSOD problem on Windows 7. Update the driver by:
  1. Going to the Asus motherboard support site
    When you reach the website:
  2. Scroll down the page and click Utilities
  3. Hold Ctrl and press f (ctrl+f) to enter the browser's find feature
  4. Search for "ATK0110 driver for WindowsXP/Vista/Win7 32&64-bit" (without quotes)
  5. Download and install the driver.
  6. After installation is complete, verify that it installed correctly.
    • Click Start Menu
    • Click My Computer
    • Go to C:\WIndows\System32\drivers\
    • Verify that the ASACPI.SYS file is dated 2009 or newer (2010,etc.)

Thanks to JMH and zigzag3143 for the above information.

No problem. Post back whether it helped or not after you've waited a sufficient amount of time (longer than it usually takes or until you get another crash). Best wishes it is stable.

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.

Unfortunately, the crash was fairly inconclusive. Possible causes are Memory problems... Corrupted hard disk file system... Corrupted System Files... BIOS... Lack of Windows updates... Antivirus Software... Backup... Hardware...


The best steps to start with based on analyzing all the reports contained in the files you uploaded:
  • Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations.

  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

Well I guess if I get another one within the next week or so that is just as inconclusive I'll just do a fresh install of win7.
